YAHOO is an acronym for 'Yet Another Hierarchical Officious Oracle.' This is the widely accepted expansion of the name Yahoo, reflecting its origins as a directory service.

You can edit an embedded organization chart object in Microsoft Office by either double-clicking the chart object or by right-clicking it and selecting 'Edit Object' (or similar options). Both methods are commonly used to open the embedded chart for editing. Therefore, option D ('A and C both') is the most accurate answer because it includes right-clicking and selecting 'Edit Object' as well as the option described in A. Option B (double-clicking) is also valid, but since both methods work, D is the best choice.

Sans serif fonts are generally preferred for large amounts of text in PowerPoint presentations because they are cleaner and easier to read on screens, especially at smaller sizes. Serif fonts can be harder to read on digital displays due to their decorative strokes.

Drop caps are used to begin a paragraph with a large initial capital letter that drops down into the lines below, making the text visually appealing and emphasizing the start of the paragraph.

You can edit an embedded organization chart object either by double-clicking the object or by right-clicking it and selecting the edit option. Both methods allow access to the editing mode of the embedded chart.

The Format Painter tool allows users to copy formatting from one part of the text and apply it to other parts, simplifying the process when the same formatting is needed in multiple locations.

Vint Cerf is widely recognized as one of the 'fathers of computer networking' for his co-design of the TCP/IP protocols, which are fundamental to the internet. Ray Noorda was a pioneer in networking but not credited as the father of computer networking. Google and Novell are organizations, not individuals.

Microsoft Word's default margin settings for 8.5-by-11-inch paper are 1 inch on all sides: left, right, top, and bottom. This standard margin setting ensures consistent formatting for most documents.

A disk is a storage medium in the form of a circular plate, commonly used to store data magnetically or optically. CPU, printer, and ALU are not storage media.

Registers are small, fast storage locations within the CPU used to hold temporary data and instructions during processing, making them a form of temporary memory. ROM is permanent memory, hard disks are long-term storage, and circuits are hardware components, not memory types.

Routing algorithms determine the best path for data packets to travel from the source to the destination across a network. This process is fundamental in networking to ensure efficient and accurate data delivery.

A logic bomb triggered by a time-related event is specifically called a 'time bomb.' It activates when a certain date or time condition is met, distinguishing it from other malware types like viruses or Trojan horses.

WhatsApp was founded in 2009 by Brian Acton and Jan Koum, who were former employees of Yahoo. Therefore, the correct answer is 'Both A & B'.

Routers operate primarily at Layer 3 (the Network layer) of the OSI model, where they route data packets based on IP addresses. Layers 2 and 4 are handled by switches and transport protocols respectively, so the correct answer is Layer 3.

Fugaku was recognized as the fastest supercomputer in the world as of June 2020, surpassing previous leaders like Summit and Tianhe-2A. It is a Japanese supercomputer developed by RIKEN and Fujitsu.

MS-DOS is a command-line interface operating system where users interact with the system by typing text commands, unlike graphical or menu-driven interfaces.

Pressing the Windows key by itself opens and closes the Start menu in Windows operating systems. The other keys (Ctrl, Shift, Alt) do not perform this function alone.

Text wrapping is the feature that automatically moves text to a new line when it reaches the border or edge of a container, ensuring the text fits within the layout without overflowing.

A modem is the device that modulates and demodulates signals for Internet connection, enabling communication over telephone lines or other media. While a NIC card is necessary for network connectivity, the modem is specifically required to connect to the Internet through certain types of connections.

Printers are commonly shared resources in computer networks, allowing multiple users to access a single device. Speakers and floppy disk drives are less commonly shared in network environments, and 'None of these' is incorrect since printers are a typical shared resource.

The basic colors used in computer graphics are Red, Green, and Blue, commonly abbreviated as RGB. These colors combine in various ways to create the full spectrum of colors on digital displays.

RAM (Random Access Memory) is volatile memory because it loses its data when the power is turned off. ROM, BIOS, and PROM are types of non-volatile memory that retain data without power.

Functional language is a type of high-level programming language that emphasizes the use of functions and avoids changing state and mutable data. Therefore, it is another name for a high-level language rather than an application language.

Serial, Parallel, and AGP are all types of ports used in computers for different purposes. Therefore, the correct answer is 'All of these' as it includes all the listed port types.

A printer driver is a type of system software because it acts as an intermediary between the operating system and the printer hardware, enabling communication and control of the printer device.
